To @ZZ whom it may concern.-

Be itknown that I, JOHN F. WILLIS, a citizen of the United States, and a resident of the city of Minneapolis, county of Hennepin, State of Minnesota, have invented a certain new and useful Improvement in YVater-Strainers, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to Water-strainers; and it has for its object to provide a strainmg apparatus of variable capacity, adapted to remove from water all foreign matter not held in solution, the parts of which are readily removable for cleansing or other purposes, and are of a construction adapted to withstand heavy pressure and rough usage.

To this end my invention may be brieiiy outlined as consisting of a closed outer shell or case constituting a receiving chamber adapted for connection to a Water-main or supply-pipe, an interior receptacle locatedv Within the outer case and above the floor of the same, having one or more iniiow pipes or openings on its upper surface, surrounded by strainer-seats and an outiioW-pipe through the wall of the outer shell,and a series of removable strainers adapted to rest on said seats and strain the Water in its passage from the outer to the inner receptacle. Each strainer is independent of every other, and is held in position on its seat by spring-tension. The top of the outer case is provided with a removable plug for access to its interior. Any strainer can therefore be readily removed without disturbing the others.

The strainers are of a special construction, adapting them to withstand the heavy pressure to which they are liable to be subjected when the apparatus is connected to city Waternlains.

Great difficulty has hitherto been found in obtaining a strainer which Would not collapse When the straining-cloth'became filled. I accomplish this end by constructing the strainer ofia set of longitudinal supports, a.

cylinder of spirally-arranged strong Wire rigidly secured to said supports, a covering of strainer-cloth secured to the spiral-Wire cylinder, and caps at the opposite ends of the cylinder, one of which is provided with au annular central opening adapting the strainer to fit over the iniioW-pipes to the interior receptacle. Y The vertical stays or supports for the spiral cylinder are preferably provided with spiralgrooves or seats for the Wire of the spiral-Wire cylinder, and when the parts are in vposition they are galvanized together, thusV makinga very rigid and strong v construction.

The accompanying drawings illustrate the invention', wherein, like letters referring to like parts throughout, Figure l is a vertical section of the entire apparatus. horizontal section on the line X X of Fig. l. Fig. '3 is a View, partly in section and partly in elevation, of yone 4of the strainers and the interior receptacle detached, some of the parts being broken away; and Fig. 4 is a plan view of a part of the interior receptacle, representing one of the strainers in po sition.

A is the exterior case, having right-angle extensions B for connection With the Watersupply main on one side, and a similar extension B on the other for connection with an outflow-pipe.

C is a removable cap-plate adapted to be secured by bolts or otherwise to the top of the case for closing the same.

D is the removable plug for closing the annular central opening in this cap-plate.

E is a removable plug closing and opening near the bottom of the case for removing the deposits in the same.

F is the interior receptacle, Which is preferably annular in form, and may be supported in any suitable Way above the' iioor of the outer case. As shown, it is held in position by its outowpipe F, Vwhich closely tits and forms a tight joint with the outer extension B of the outer case.

f are the inoW-pipes projecting from the top surface of the receptacle F,

f are slightlyqaised annular shoulders surrounding the inflow-pipes and constituting seats for the strainers.

f is a gasket or packing, of rubber or other suitable material, resting upon the seats f.

G are the strainers. l

g are the vertical supports, provided with spiral grooves or wire seats g. g is the Fig. 2 is a spiral-wire cylinder surrounding these supports and galvanized thereto.

g" is the covering of wire-cloth secured to the spiral-wire cylinder.

g is the upper cap, and g the lower cap, of the cylinder. The opening in the lower cap-plate is of greater diameter than the diameter of the inflow-pipe f. The cylin` der tits over the intlowpipe and the lower cap-plate rests on the gasket f, thus forming a water-tight joint with the receptacle F. H is the spring for holding the cylinder in position. It is secured to the top of the upper cap 9. and is free at its upper end. When placed in position, the spring is bent down and bears against the cap-plate C, as shown in Fig. l.

The size of the outer and interior receptacles and the number of strainers used will vary according to the capacity required.

The operation is evident from the description. Vater comes into the outer case through the inflow-pipe B and is strained in its passage through the strainers G. The strainedwater passes out through the outflow-pipe F. Such of the foreign matter as does not fall to the bottom of the outer receptacle by its own ,y weight is caught on the outside of the vstrainers cloth. Vhenever the strainers become clogged, all that is necessary in order to clean them vis to remove the plug D, press down'the spring H, and lift out the cylinder, one ata time. The difference in the diameter of the lower cap g of the strainer-cylinder and iniow-pipe f of the interior receptacle allows necessary lateral movement for this purpose.

This apparatusis particularly well adapted to remove from the water sawdust and similar floating material. It should, however, be

noted that the relative location ot the difterentpitrts is such as to afford a settling-chambeuin/ the lower end of the outer case for VliatI claim, and desire to secure by Letters Patent of .the United States, is as follows:

l. In water-straining apparatus, a strainer consisting v of grooved supporting-rods, a vwire cylinder the coils of which are rigidly secured in the grooves of said rods, and a covering of strainingmaterial attached to said cylinder, substantially as set forth. Y Y

y stantially as set forth;

one or more independent removable strainers mounted on said interior receptacle and 1n communication therewith, and a pressure device for retaining each strainer in position on its seat, substantially as described.

4. Thecombination, with a' receiving-case having its iniiow-pipe above the level of its bottom, of an interior receptacle supported above the bottom, having an outflow-pipe through the wall of the outer case and provided with a series of vertical inflow-pipes, a series of strainers fitting over said inflowpipes and resting on packed seats surround- .ing the same, springs on the top of said strainers, bearing against the end of the outer case for retaining them in position, and a removable plug in the end of the case, substantially as described.

5. The combination, with the outer vertical case having a removable plug in its upper end, of the independent interior horizontal outflow-receptacle therein, having ajseries of inflow-pipes with surrounding strainerseats on its upper surface, and a correspond'- ing series of independent strainers having 'openings in their lower cap-plates vof larger diameter than said vertical iniowpipe, adapted to fit over said pipes and rest upon said seats, whereby the strainersmay be tilted at their tops as is required for removal, A substantially as described'. catching the'mud and sand and other heavy j consisting of grooved supporting-rods, a wireV cylinder surrounding said rods and secured in the grooves thereof, a covering of straining material attached to said cylinder, and a' cap-plate at each end of said cylinder, sub` JOHN F. NVIELISL In presence of- J as. F. WILLIAMSON, EMMA F. ELMORE.
